ISO-CHEK Cassettes
Suitable for most isocyanates, the patented ‡ ISO-CHEK sampling system uses a two-stage filter that results in the simultaneous collection and separation of vapour from aerosol at the point of collection.
- Accurately samples diisocyanates: HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI
- The only filter-based system that simultaneously traps and separates both monomers and oligomers
- For better determinations of control strategies
- Decreases sample preparation and analysis time by 40% compared to other methods
- Pre-made calibration standards are available
- Highly stable — minimizes storage and handling
- Highly sensitive analysis provides detection limits below current regulated exposure levels
- Ideal for occupational sampling and environmental surveys
- Requires only a 15-minute sample time
- Meets the specifications of several methods
- ASTM D5932 for 2,4, 2,6-TDI
- ASTM D6561 for HDI
- ASTM D6562 for HDI
